I have had several people PM me asking about the audio pucks I used on my son's bed, my Jawa, and my R2 projects. These are far from ideal when compared to all the other options out there for audio, but these are easy to find and easy to work with in my opinion. They cost about $8.00 in the store, but I have seen sellers online offering them for a bit less.

Here's how I converted them to work off a standard momentary push button switch.

Here's how it looks out of the package. You should record the audio BEFORE attempting this conversion. Although you can change the audio after, it's kind of a pain. These come with instructions for recording, but it's basically holding it next to a speaker and pressing the record button.

The top comes off real easy, just push in the side tabs and it lifts off. You're going to remove the white button and two rubber buttons. Just pull them straight off. I would keep one of the rubber buttons in the event you wish to re-record audio down the road.

You should note that the center circuit is the activation circuit for replaying your audio. The other circuit (circled in red) is for recording. It's important not to touch this circuit when working, if you do, you just erased your audio.

Take a flathead screwdriver, or other sharp, flat tool, and GENTLY scrape off a small portion of the green film over the two pictured circuits. You just want to expose a small bit of the metallic filament.

It should be noted that throughout this process you'll probably activate the sound at least a dozen times. If it annoys you, just remove one of the batteries until you're done.

Again, these aren't the best quality, but depending on your project, it's complexity, and your budget, these just may work for you.

Hope that helps!

Build-A-Bear sells them, looks like they have a few stores in Australia. Otherwise, just search for audio disc on the web, I think eBay even had a few.

When I say not ideal, I mean that for the people who opt for higher quality audio and will use an MP3 player with a nicer speaker, or a high quality sound board / wired speaker. This is just an inexpensive and easy way to add audio in my opinion.

Re: azheat01's Build-A-Bear Audio Puck Tutorial

Thanks for that Azheat. After looking up build a bear I found the device you used on the US website, but there is no such device on the australian website. (I did get a kick out of the page themesong, give it a listen if you have time!). And websearching audio disc, audio puck and various 'playback' devices yielded poor results. But! After a thorough ebay search (these things were tricky to find) i found this "Audio Record and Playback Module Kit - ISD1730" Audio Record and Playback Module Kit - ISD1730 | eBay
12bucks from hongkong, only 20 second playback duration, which is not ideal, but im thinking maybe i could possibly re-wire a few to get a longer playback time. I think there basically just like DIY sound kits for DIY robots.
Thank you AZheat! have been a big help ! :)
